6. a) Assign all peaks in the following 1H-NMR spectrum.
b) What is the ratio of peak areas for these three peaks?
c) Below this spectrum, draw a sketch of what you would expect to see if you added D2O to this sample.
7. Predict the structure of the molecule whose 1H NMR spectrum is shown below. When D2O is added to this sample and the spectrum is rerun, the peak at 7.3 disappears.
